The purpose of this research is to determine the effectiveness of a coordinated program (Dyad Plus) that would help to facilitate self-monitoring, positive communication, joint problem solving, and social support to increase physical activity, healthy eating, and weight loss. Participants of the Brenner FIT (Families In Training) pediatric weight management program and their parent/guardian will co-enroll in weight loss programs. Parents/guardians will receive the components of By Design Essentials.

Brenner FIT Standard
BehavioralAfter referral, families attend an orientation, in which they are then scheduled for an initial introductory 2-hour intake group session and cooking class; these occur within 2-4 weeks of the orientation. Monthly 1-hour long visits with the dietitian, counselor, and physical activity specialist are held for 6 months, in which the child and caregiver see the pediatrician. During the 6 months of treatment, they attend 4 group classes, choosing from topics such as meal planning, physical activity, and parenting. Specialized visits with the physical activity specialist or dietician are scheduled as pertinent issues arise. Clinic visits include individualized goal setting (for behaviors family/clinician have agreed to address), healthy eating and physical activity education, and behavioral counseling to implement changes at home.
By Design Essentials
BehavioralA dietitian provides each participant with a detailed program manual that describes the prescribed diet. The dietitian utilizes standard behavioral techniques to promote lifestyle behavior changes that enable participants to implement and maintain behaviors necessary to adhere to the dietary prescription. Participants also receive a standard exercise program designed to promote exercise energy expenditure of approximately 600 kilocalories\*/week. The exercise prescription includes resistance training for 2 days per week and aerobic training for 3 days per week, to meet a 600 kilocalories\*/week expenditure goal. Behaviorists meet with participants to provide individual and group-based counseling to learn the skills necessary to adopt the prescribed dietary pattern and exercise plans. Group sessions will be delivered consecutively over 6 months (20 total; 1.5 hours each).
Dyad Plus
BehavioralThis will include all components of the standard Brenner FIT program and By Design Essentials. In addition, group sessions, one-on-one parent/child communication sessions, joint goal setting/tracking, and home environment assessment. Dyads will attend 6 meetings that will last approximately 1 hour each.
BMI z-score
Weight status of caregivers and youth will be quantified through calculation of BMI derived from measurement of height and weight at the intake and follow-up visits. Both height (plus or minus 0.1 cm) and weight (plus or minus 0.5 kg) will be recorded twice and values will be averaged to produce the final value using a Tanita (registered trademark) digital scale and a Seca (registered trademark) Height Rod (respectively). BMI will be calculated as kg /m2. BMI z-score will be calculated using CDC growth charts.

Feasibility and Acceptability of Implementation
We will examine screening, recruitment, retention, adherence, and overall perception of Brenner FIT and By Design components
Physical Activity Assessment Tool (PAAT)-Adult
Physical activity data will be collected using the Physical Activity Assessment Tool (PAAT). The PAAT measures type, frequency, and duration of moderate and vigorous physical activity from all four domains of physical activity-leisure, occupational, household, and transportation-in the last 7 days, and asks if this is "more, less, or about the same as usual" activity

Physical Activity Assessed with Youth Physical Activity Questionnaire (YPAQ)
Physical activity data will be collected using the Youth Physical Activity Questionnaire (YPAQ which contains 47 different activities broken into contextual settings/domains: sporting, leisure, school, and free-time activities and aims to measures frequency, duration, intensity, and mode, over the past 7 days of both PA and sedentary activities. The questionnaire will be self-administered via a REDCap survey. Study staff will be available to answer any questions that participants have during the process.
